Fix an image to exact upload requirements
Exact pixel dimensions, JPEG or PNG output, and a guaranteed maximum file size — with verified presets for specific portals.
How it works
- Your image is processed on a canvas in your browser; nothing is uploaded.
- Choose a verified requirement preset or enter dimensions and a size cap yourself.
- JPEG quality is auto-tuned until the file fits under your size limit.
- Output is standard sRGB, and camera EXIF/GPS metadata is not carried over.
